Q: I have a 3100psi Generac model 60242 I purchased from PED. Works great. I have noticed lately that when I tilt the unit back in order to reposition it, it will suddenly quit. Is this the "Oil Alert System" sensing a drop in oil level and shutting down the engine? The unit restarts after a couple of pulls.
by Dave from North Carolina on June 05, 2014

A: It could be the Oil Alert sensor, or an adjustment needed in the carburetor... The good news is this unit comes with a 2 year Factory Warranty from the folks at Generac.

You can use their Service Center Locator to find your local Authorized Repair facilities, or give them a call at (888) 436-3722 x5381.

Please be sure to have the serial number of your pressure washer handy if you call Generac; they usually ask for it. You will need a copy of your invoice for any warranty work- just click on My Account in the upper right corner of our website and follow the prompts to print one out.

If there are several repair locations in your area you may want to call around to see which one has the shortest turn-around time so you get your pressure washer back as quickly as possible.

Q: Hi...I see the site sells extended warranties. Who covers these, and what's covered. Also, is it worth it to go beyond the two year Generac offers.
by Brian Warehime from New York on May 29, 2014

A: The Extended warranty is covered by WarrenTech. They will start the day after the manufacture warranty and cover all non wearable items. Things that would not be covered would be items like the hose, gun, wand. They would have you take it to a local service center. I feel the Generac Warranty is great. However, if you would like extra time after that it is available for purchase.

Q: I am looking for recommendation on accessories needed for the Generac 6598 to easily clean siding and gutters on a large 2 story house.
Thanks.

by Jared from Florida on May 08, 2014

A: I definitely recommend a telescoping wand and gutter cleaner attachment for your application. If you would like to spray detergent through the telescoping wand you will need to go with an aluminum one. I have included link to the telescoping wand, gutter cleaner, adapter needed to attach to your high pressure hose, and the detergent I recommend.

Q: I'm buying a generac gas model# 6598 from you guys and am looking at MTM hydrojet turbonozzle to go with it.What size orifice should I get? We have a two story home (30' to gable ends) will MTM Hydro long-range detergent foamer work?
by Bruce E Lawrence from Maine on April 17, 2014

A: You should get a 3.0 Orifice Turbo Nozzle. Turbo Nozzles are meant to increase cleaning speed and efficiency, not for long distances. I have attached a link for you.

3.0 Orifice Turbo Nozzle

For your two story home and gables I would go with model 100145. This product allows you to reach up to 3 stories high. I have included a link to this as well.

Model 100145

Both of these product will quick connect on to the end of your lance where the colored spray tips usually go.
by Mike, Product Expert
Q: Will the Generac 6598 connect to a foam cannon like the MTM Hydro without needing any additional hardware?
by Doug from Rhode Island on April 15, 2014

A: Yes, you can purchase the MTM foamer model 14.0263. This has a fitting on it so that it quick connects into where your colored spray tips usually go, so no additional hardware is needed. I love this foamer!

Q: What is the pump made out of?
by Zach from Minnesota on April 14, 2014

A: This unit has an AR axial cam pump with a brass head on it. It is a step above the rest in it's category. The brass head dissipates heat more effectively, therefore increasing the life of the pump.
by Mike, Product Expert
Q: Is there a telescoping spray wand available for the
Generac Model 6598?

by Carmen Fontana from Delaware on April 13, 2014

A: Yes, if you would like to be able to dispense detergent I recommend the 24' Aluminum Telescoping Wand. I have also included the adapter you will need to connect this product to your high pressure hose.

Q: If you go to Lowes, they still carry the model 6024. You show that model as being disconntinued. The 6598 seems to match up with the 6024, spec for spec. Is there any difference? Why wouldn't Lowes carry the 6598?
by Mark from Connecticut on March 19, 2014

A: The 6024 is the old model number. The new model number is the 6598. It has all the same components as the 6024, just different colors to make it more appealing.

Pressure Washers Direct Recommended

Given the oversized 212cc Generac brand engine and the durable AR brand axial cam pump, this model is great choice for any homeowner looking to purchase a very good quality pressure washer without putting a large hole in their wallet.

The frame on this unit, like all of the other Generac pressure washers, is a very well thought out design with the consumer in mind. It's balanced and easy to maneuver with 2 easily accessible detergent tanks at the bottom. This model has a vertical frame... more

Good Purchase
I purchased this model (6598) instead of the Generac One Wash since this design has been around longer and has a good track record. I have been very happy. Here are a few highlights from my experience thus far:

- Assembles out of the box in 10-15 minutes... very simple.
- Some plastic used in cosmetic areas, but high quality construction where it matters.
- Unit is balanced making it easy to tote around the house.
- Has a generous amount power and water output. very happy!!
- Engine... more
Pros: Easy To Use, Price, Exceeded Expectations

Hard To Start & Running Rough
Fast delivery & easy set-up. The unit was hard to start and ran very rough. Can't be returned since it has had fuel in it. Authorized warranty repair shop should be able to get to it in a couple of weeks. And now the unit is on sale.
Cons: Low Quality
Mike, the Pressure Washer Expert
Product Expert
Pat,
I am sorry to hear your pressure washer isn't running well; I understand how disappointing that can be.

I see from your file that there are several Generac Authorized repair locations in your area- I hope you called around to find the one with the shortest turn-around time? During the summer months I realize they get busy.

It is Federal Law that prevents shipping an engine that has had gas in it, since it's a fire/explosion hazard. That's why we only sell products with national service networks.

For folks reading this review, there are a couple tips for new engines. First is to use fresh gas- the stuff you've had sitting around for the lawn mower may have lost a lot of its volatile compounds and won't burn well.

Second is to hook up the water to the unit, then pull the spray gun trigger and let the water run for a minute without starting the engine. This drives out all the air from the pump, preventing vapor lock. Since the pump and engine are connected directly, vapor lock can make it very difficult to get the engine to turn over.

We post the best prices we can every day. Occasionally manufacturers will run specials where they provide bonus items or a special price for sales that happen in a specific time period. Unfortunately they won't provide credits for sales that happen outside their time period. We appreciate your business, and apologize for any inconvenience.

Good Product
This washer is well worth the money. It has good pressure and the engine fires right up each time use it.

I personally would like to see the frame a little heavier but will recommend to my friends.

Owned For 2 Months And Haven't Been Able To Use Yet.
Bought 3100 washer May 5. On/off switch fell off first time I tried to use it. 7 weeks to get a 5 dollar part. Finally got it back and when I tried to use it it ran for 60 seconds and died. Will not start. Back in the shop again.

Andy,
I am so sorry you are having problems with your pressure washer. I've been working with the folks at Generac, and they've agreed to swap out your pressure washer. I left you a voice mail and emailed you directly asking you to contact me so I can explain in detail.

We appreciate your patience, and I look forward to hearing from you!

Great Machine For The Price
The pump on my old Honda 2200 pressure washer died so I decided to replace it with the Genrac 3100 psi. It was easy to assemble and started on the 2nd pull.

I pressure washed my wood deck, my pickup and patio furniture. It worked as I expected. Glad I made the choice I did.

Great machine!!
Pros: Easy To Use, Price, Easy To Store, Light Weight

Never Had One
Never owned a power washer but I have operated many. After lots of research I bought this one.

I had some trouble getting it to crank the first time and I thought I made a bad purchase. After using it now for a couple of months it always starts on the second or third pull.

It does a great job on everything I have tried it especially concrete! I hope it lasts a long time because it is a workhorse!
Pros: I'd Buy It Again, High Quality, Light Weight, Reliable

Good Quality Pressure Washer
Received the Generac four days after placing the order. Assembly was easy and after adding gas and oil, the engine started on the second pull.

This thing has plenty of power. Immediately went to work cleaning vinyl siding. The only thing I have to add is a longer high pressure hose as the one provided is somewhat short.

Good Value For A Consumer Machine, But...
Item arrived on time but the fuel tank and cap were damaged in shipping, but not to the point that it would not work, so I let that go.

Machine is designed so that the pressure hose can come into contact with the hot muffler, which melted a hole in the hose when I was using it for the first time. Had to stop my project and drive into town to buy a replacement for $65.00 @ Home Depot. Not too happy about that.

This is not a high quality machine but so far a good value for the money.

Chris,
You may be beyond the short window to report shipping damage to the folks at FedEX to cover the cost of repair or parts since your order was delivered on 5/13/14.

You can use their FedEX Online Claims using the tracking number we emailed to you, and posted to your account.

Hot mufflers are always a hose hazard with gas-powered pressure washers. There is a knack to keeping an eye out behind you to manage your hoses while you're pressure washing; you also need to prevent any kinks from forming in the hose since they will burst after just a few seconds under pressure.

We appreciate your business and apologize for any inconvenience.
